The effects of the Nordic hamstring exercise on sprint performance and eccentric knee flexor strength: A systematic review and meta-analysis of intervention studies among team sport players

The primary aim of this study was to investigate the effects of the Nordic hamstring exercise (NH E ) on sprint performance (i.e., 5, 10 and 20 m) and explore associations between study characteristics and sprint outcomes in team sport players. Secondary aims were to (1) investigate the effects of the NH E on eccentric strength of the knee flexors (ES KF ) with categorical subgroup analysis to determine differences between recreationally, well-trained individuals and young athletes, (2) determine the relation between ES KF and sprint performance in team sport players, and (3) explore the effect of study characteristics (i.e., weekly volume, time duration and body mass) on ES KF .Medicin

Relationship between Anterior Cruciate Ligament Injury and Subtalar Pronation in Female Basketball Players Case-Control Study

Anterior cruciate ligament (ACL) injuries are a common issue in basketball. Several studies point to subtalar pronation as a relevant risk factor for these injuries, despite their multiarticular and multiplanar nature. This study evaluated the correlation between subtalar pronation and ACL injuries in female basketball players. A total of 30 players were recruited and divided into two groups: 15 with previous ACL injury and 15 without injury. The navicular drop test (NDT) and drop vertical jump test were applied to quantify parameters such as navicular drop, calcaneal eversion, ankle dorsiflexion, knee flexion, and dynamic valgus. The results showed significantly higher NDT values (6.93 ± 1.64 mm vs. 5.41 ± 1.96 mm, p = 0.029) and maximum calcaneal eversion angle (10.94 ± 3.22◦ vs. 5.30 ± 3.33◦ , p < 0.001) in the injured group. There were also significant differences in maximum dynamic valgus (152.73 ± 15.00◦ vs. 165.26 ± 5.628◦ , p = 0.005) and knee flexion (93.70 ± 7.47◦ vs. 82.92 ± 11.14◦ , p = 0.004) between groups. These findings suggest that subtalar pronation, assessed by NDT, and calcaneal eversion could be indicators of higher susceptibility to ACL injuries in female basketball players.Fisioterapi

Effects of ankle position during the Nordic Hamstring exercise on range of motion, heel contact force and hamstring muscle activation

One of the main benefits of the Nordic Hamstring Exercise (NHE) is that it can be performed without the need of any extra material. However, numerous technical execution variables such as the ankle and pelvis position can influence the performance. The primary aims of this study were to investigate the effects of ankle position (i.e., plantar or dorsal flexion) on Nordic Hamstring Break Point (NHBP), repetition time and heel contact force. A secondary aim was to investigate differences in biceps femoris long head and semitendinosus muscle activation. Male professional field hockey players (n = 12) volunteered for the study. Paired t-tests were used to analyse the effect of ankle position on muscle NHBP, eccentric peak torque and repetition time. Ankle dorsal flexion resulted in a higher NHBP (p = 0.002, effect size [ES] = 1.48 [0.57 to 2.38]), repetition time (p = 0.004, ES = 0.98 [0.24 to 1.72]) and both absolute and relative heel contact force (p = 0.028, ES = 0.67 [0.01 to 1.34], p = 0.017, ES = 0.76 [0.07 to 1.44], respectively) compared to plantar flexion. Muscle activation was not significant different. This study showed a higher NHBP, absolute and relative heel contact force and repetition time with a dorsal flexed ankle vs. a plantar flexed ankle in the NHE, without changes in hamstrings muscle activation.Medicin

Impact of Pain Neuroscience Education Program in Community Physiotherapy Context on Pain Perception and Psychosocial Variables Associated with It in Elderly Persons: A Ranzomized Controlled Trial

This study investigated the long-term effect (six-months) of a Pain Neuroscience Education (PNE) program on pain perception, quality of life, kinesiophobia and catastrophism in older adults with multimorbidity and chronic pain. Fifty participants (n = 50) were randomly assigned to the pain education therapy group (PET; n = 24) and control group (CG; n = 26). The PET group received six sessions (i.e., once a week, 50 min) about neurophysiology of pain while the CG carried on with their usual life. Perception of pain through the visual analogue scale (VAS), quality of life (EQ-5D questionnaire), kinesiophobia (TSK-11) and catastrophism (PCS) were assessed after six months since the last PNE session. Statistically significant differences on VAS (t(48) = 44, p = 0.01, ES = 0.42 [0.13, 0.65]) was found in favor to PET group. No other statistically significant differences were found. This study found that the application of a PNE intervention in an isolated form was able to significantly reduce pain perception with low effect size in the long-term (six months after intervention) in elderly people with chronic pain.Medicin

Hip adduction and abduction strength profiles in elite and sub-elite female soccer players according to players level and leg limb-dominance

Background: Understanding the hip adduction and abduction strength in female soccer players is crucial for performance enhancement and injury prevention. This study compares the strength profiles in these muscle groups between elite and sub-elite female soccer players and assesses the impact of leg limb-dominance. Methods: A descriptive-comparative study was employed. Eighty-two female soccer players were evaluated. Isometric hip-adduction and abduction strength were measured using a handheld dynamometer. Results: Female elite and sub-elite soccer players displayed a mean and standard deviation (SD) on isometric hip-adductor strength for dominant (3.19 Nm/kg ± 0.69 vs. 2.40 Nm/kg ± 0.67) and non-dominant leg (3.32 Nm/kg ± 0.76 versus 2.42 Nm/kg ± 0.70), respectively. For isometric hip-abductor strength in elite and sub-elite players, a mean and SD of dominant (2.86 Nm/kg ± 0.56 vs. 2.07 Nm/kg ± 0.50) and non-dominant (2.80 Nm/kg ± 0.59 vs. 2.04 Nm/kg ± 0.43). In essence, elite players were stronger than sub-elite players on isometric hip-adduction (mean difference [MD] = 0.82 Nm/kg, CI95% = 0.42–1.12) and abduction (MD = 0.83 Nm/kg, CI95% = 0.54- 1.12) both in dominant and non-dominant, leg, whereas no differences existed for hip adduction:abduction ratios between groups and legs. Conclusions: Elite female athletes exhibited greater strength than sub-elite female players in both hip adduction and abduction, whereas adduction:abduction ratio values did not differ between the two groups or between different legs

Eficacia analgésica del tratamiento invasivo miofascial (punción seca) en fibromialgia

Estudios previos sugieren que la sensibilización central es la explicación más plausible para entender la etiopatología de la fibromialgia. El tratamiento de los ountos gatillos miofasciales a través de la punción seca se ha demostrado útil como tratamiento de la fibromialgia para disminuir el dolor generado por la sensibilización central. Sin embargo dentro del nuevo modelo biopsicosocial de dolor, los pacientes con fibromialgia se caracterizan por tener altos niveles de pensamientos negativos, denominado, catastrofismo. Esta situación aumenta de intensidad las experiencias dolorosas y puede determinar la eficacia de diferentes tratamientos. El objetivo de nuestro estudio fue valorar como los niveles de catastrofismo podían influir en la eficacia de la intervención y en la percepción dolorosa de la técnica durante la intervención, despúes de la misma y 24 horas tras el tratamiento.Prior studies suggest central sensitization plays an important role in the pathophysiology of fibromyalgia. Dry needling trigger point treatment, while painful, has been demonstrated as useful in fibromyalgia patients for decreasing pain and central sensitization. However, the current biopsicosocial pain paradigm indicates that fibromyalgia subjects with high levels of catastrophism have negative thoughts related to potentially painful episodes, which results in a major amount of pain perceived and efficacy of the treatment. Therefore, the objective of our study was to assess whether catastrophizing could influence the perception of pain during, after and 24 hours after dry needling application

Influencia del catastrofismo durante y después de la punción seca

Treball final de Màster Universitari en Ciències de la Infermeria. Codi: SAV017. Curs acadèmic 2013-2014Antecedentes: La sensibilización central desempeña un papel importante en la fisiopatología de la fibromialgia. El tratamiento de los puntos gatillo mediante punción seca, resulta ser útil para disminuir el dolor y la sensibilización central. El actual paradigma biopsicosocial del dolor, indica que los sujetos con fibromialgia presentan altos niveles de catastrofismo. Dichos sujetos tienen pensamientos negativos relacionados con episodios potencialmente dolorosos, lo que se traduce en una mayor cantidad de dolor percibido. Objetivo: Evaluar si el catastrofismo puede influir en la percepción del dolor durante y después de la técnica. Metodología: Estudio clínico aleatorizado a doble ciego. El grupo experimental fue formado por sujetos diagnosticados de fibromialgia y el grupo control por sujetos sanos. Los integrantes de ambos grupos fueron asignados al azar para ser sometidos a punción seca real o simulada. Se evaluó el nivel de catastrofismo (versión española de la escala de catastrofismo del dolor) antes de la intervención en cada sujeto y el dolor percibido durante e inmediatamente después del procedimiento (escala analógica visual de dolor, PVAS). Resultados: Cuarenta y nueve mujeres, tanto sanas como fibromiálgicas, completaron el estudio. Tras el análisis se encontraron diferencias significativas en el dolor percibido durante el tratamiento con punción seca (PVAS, p < 0,0001) pero no después de dicha intervención (p = 0,06). Conclusión: Los niveles altos de catastrofismo tienen una influencia fundamental en la percepción del dolor durante la utilización de esta técnica. Este estudio sugiere que comprobar este factor durante la punción seca es esencial para la implementación de esta intervención.Background: Central sensitization plays an important role in the pathophysiology of fibromyalgia. Dry needling trigger point treatment, while painful, has been demonstrated as useful in fibromyalgia patients for decreasing pain and central sensitization. However, the current biopsicosocial pain paradigm indicates that fibromyalgia subjects with high levels of catastrophism have negative thoughts related to potentially painful episodes, which results in a major amount of pain perceived. Therefore, the aim of our study was to assess whether catastrophizing could influence the perception of pain during and after dry needling application. Methods: A randomized, double-blinded, placebo-control group study was conducted with subjects diagnosed with fibromyalgia or healthy. They were randomly assigned to real dry needling or simulated dry needling group. We assessed the level of catastrophism (Spanish version of the pain catastrophizing scale) before intervention in each subject and the perceived pain during and immediately after the dry needling procedure (visual pain analogue scale, PVAS). We used the Fibromyalgia Impact Questionnaire to evaluate the subjects. Results: Forty-nine female subjects completed the study, either healthy or fibromyalgic. We found significant differences in pain perceived during the dry needling (PVAS, p < 0.0001) but not after the dry needling intervention (p = 0.06). Conclusion: High levels of catastrophizing have a fundamental influence on the perception of pain. This study suggests checking the role of this factor during invasive treatment is essential for the implementation of this intervention
